Bug when use chain and GeoIp2 at first position with cache

GeoIp2 return empty collection and save it in cache after that next providers(custom) load from cache empty collection instead of using his code

  $result = json_decode($this->executeQuery($address));

        if (null === $result) {
            return new AddressCollection([]);
        }

$result = json_decode(''); //NULL

private function executeQuery(string $address): string
    {
        $uri = sprintf('file://geoip?%s', $address);

        try {
            $result = $this->adapter->getContent($uri);
        } catch (AddressNotFoundException $e) {
            return '';
        } catch (AuthenticationException $e) {
            throw new InvalidCredentials(
                $e->getMessage(),
                $e->getCode(),
                $e
            );
        } catch (OutOfQueriesException $e) {
            throw new QuotaExceeded(
                $e->getMessage(),
                $e->getCode(),
                $e
            );
        }

        return $result;
    }

I think there should not be return '';, but there should be fatal

 public function geocodeQuery(GeocodeQuery $query): Collection
    {
        foreach ($this->providers as $provider) {
            try {
                $result = $provider->geocodeQuery($query);
                if (!$result->isEmpty()) {
                    return $result;
                }
            } catch (\Throwable $e) {
                $this->log(
                    'alert',
                    sprintf('Provider "%s" could geocode address: "%s".', $provider->getName(), $query->getText()),
                    ['exception' => $e]
                );
            }
        }

        return new AddressCollection();
    }

\Geocoder\Provider\Chain\Chain::geocodeQuery now always return empty collectioon \Geocoder\Model\AddressCollection();

从 GeoIp2 provider 的 executeQuery 和 geocodeQuery 方法开始，然后跟踪 Chain::geocodeQuery 如何处理来自第一个 provider 的空 collection，以及如何为后续 provider 读取 cache。复现一个将 GeoIp2 放在首位、将自定义 provider 放在第二位的 chain；当 GeoIp2 的空响应不再阻止使用后续 provider，并且预期的错误行为已得到验证时，即表示完成。
